Technical Background: Under extreme driving conditions (e.g. long idle periods or extended stop and go traffic), high temperatures build up in the rail system and can lead to steam bubbles in the fuel. This causes temporary drops in fuel pressure, causing DTC P008700 (fuel rail pressure too low) to be stored. Freeze frame data will indicate those extreme driving conditions: coolant temperature is above 102? C.
Production Solution: Software to optimize the cooling strategy to solve this issue is currently in development.
